When trying to open a file with C-O, kate crashes with (kate:2612): Gdk-WARNING **: gdkwindow-x11.c:5555 drawable is not a native X11 window Segmentation fault (core dumped) Current workaround is to start kate with: GDK_BACKEND=x11 kate Reproducible: Always Steps to Reproduce: 1. press C-O with a wayland session running gnome-shell (wayland) with Xwayland on arch linux.
We use the native dialogs via QFileDialog, if that keeps to be an issue, please report that upstream to Qt.
